The remaining arcade, versus, survival and Medal of Millionaire modes are little more no-nonsense, but any shortcomings are made up for by a flawless head-to-head ad-hoc mode. Be warned, though: two PSPs means four speakers, which makes squeaky characters like Jam twice as irritating.
The other game on the UMD, Judgment, is a side-scrolling brawler along the lines of Final Fight. It's pure button-mashing mayhem, with players wading through hordes of huge, beautifully drawn monsters and slashing them to pieces.
Judgment is the sort of thing that might normally be a throwaway extra, and while its story certainly is, the developers put a huge amount of care into everything else. Everything from the backgrounds to the gigantic, crazy-looking boss monsters is as meticulously drawn and animated as the main characters, and there's plenty of variety in the level design. The two-player co-op makes things even more chaotic and fun, and if that's not enough, consider that you'll also get to ride a robotic, laser-breathing dinosaur through a few of the later stages.
Only five characters are selectable at first - Sol Badguy, Ky Kiske, Amy, Millia Rage and I-No - but you can unlock up to 20 (Kliff, Justice and Robo Ky are missing) by playing through the story mode. In addition to said slew of characters, Judgment packs in a good chunk of their special moves, making this a lot deeper than your average brawler.
